Hey! Here's some background: I'm in love with a k90 setup strung with Pro Supex Big Ace at 50lb. However, typically, true love starts several hours after hitting with a fresh string job. This string has been great for me since it's pretty much the only polyester that is still amazing after it dies (unlike, for example, Cyberflash). In fact, I like it most when it starts to die - you get such nice power, precision, and spin on command all with a very relaxed stroke. This is actually why I'm using it - I don't want to have to restring after every second hit. This setup only seems to start to lose its qualities after a few weeks. However - I'm wondering, would decreasing the tension even more help towards this kind of a powerful feel earlier on in the string's life? Has anyone tried similar polyester strings at even lower tensions? I know frame size is also a factor that affects relative stiffness of a string bed (ie/ a 50lb on a 90 sq inch is not the same as a 50 on a 100 sq inch) - but how low can you go before decreasing tension starts to negatively impact power? Does anyone know any other setups that feel this good even after they're dead? I string my own rackets so I have no problem testing things out. If I remember correctly, Wilson Sensation seemed to play fairly well for me even after a while. Thanks!
